The Chilean recluse spider, Loxosceles laeta, is a highly venomous spider of the family Sicariidae. In Spanish, it (and other South American recluse spiders) is known as araña de rincón, or "corner spider"; in Brazilian Portuguese, as aranha-marrom or "brown spider". The recluse spiders ( Loxosceles ( / lɒkˈsɒsɪliːz / ), also known as brown spiders, fiddle-backs, violin spiders, and reapers, is a genus of spiders that was first described by R. T. Lowe in 1832. [4] They are venomous spiders known for their bite, which sometimes produces a characteristic set of symptoms known as loxoscelism .

Scientific name: Loxosceles laeta Physical Description and Identification Adults Size: Being a large recluse species, its size ranges between 8mm and 40mm (0.31 to 1.57 inches). Color: Like most other recluse varieties, the Chilean recluse also has a brown body with a black line emerging from the upper part of its thorax resembling a violin. The common name "brown recluse spider" refers to one species of spider, Loxosceles reclusa,. Finally, in Chile where L. laeta is native, a spider census turned up an average of 163 live violin spiders living in the 5 most infested homes (range 106 to 222 spiders). And no one living in those houses had ever shown evidence of a recluse bite. The Chilean recluse spider, Loxosceles laeta, is a highly venomous spider of the family Sicariidae. It usually hides in cracks and corners that are difficult to access, hence its name. It is considered the most dangerous of the spiders of the genus Loxosceles, since its bite frequently produces severe systemic reactions and even death. The Chilean recluse spider is a venomous spider, Loxosceles laeta, of the family Sicariidae (formerly of the family Loxoscelidae). In Spanish, it (and other South American recluse spiders) is known as araña de rincón, or 'corner spider'; in Portuguese, as aranha-marrom or 'brown spider'.

Loxoscelism ( / lɒkˈsɒsɪlɪzəm /) is a condition occasionally produced by the bite of the recluse spiders (genus Loxosceles ). The area becomes dusky and a shallow open sore forms as the skin around the bite dies ( necrosis ). It is the only proven type of necrotic arachnidism in humans. Chilean Recluse Spiders ( Loxosceles laeta) are highly venomous spiders of the family Loxosceles. This type of spider is native to South America and lives in a wide range across several South American countries. The Chilean Recluse Spider is extremely dangerous and is one of the most venomous of all recluse spiders.

The Chilean Recluse Spider, also known by its scientific name Loxosceles laeta is an extremely dangerous and somewhat common spider. While the entire recluse family of spiders is known to be dangerous, this particular species is among the most venomous. Not a spider to be messed with! Recluse spider populations can grow to hundreds or thousands in a single structure such as a house in Kansas (USA) where 2,055 L. reclusa spiders were collected in a 6-month period and in a Chilean study where 29 % of the inspected homes had Loxosceles spiders; the five most densely infested homes yielded an average of 163 L. laeta specimens .
Size: These spiders have a length of about 7 to 12 mm (0.27 to 0.47 inches). Color: Most species of the recluse family have a dark brown body, while the color ranges may vary from white, blackish gray, or dark brown. Other characteristics: Most of them possess six eyes arranged in groups of three. Loxoscelism is a term reserved for reactions to bites of the brown recluse spider and members of that same genus ( Fig. 14.11 ). Brown recluse spiders are normally found outdoors—under rocks, cliffs, and areas that afford protection—but this spider readily adapts to indoor habitats as well.

In synonymy: Loxosceles alicea Gertsch, 1967 = Loxosceles rufescens (Dufour, 1820) (Zamani, Mirshamsi & Marusik, 2021: 673). Loxosceles bicolor (Holmberg, 1876, removed from S of L. rufipes) = Loxosceles laeta (Nicolet, 1849) (Gertsch, 1967a: 149). Loxosceles bolivari Gertsch, 1958 = Loxosceles devia Gertsch & Mulaik, 1940 (Gertsch & Ennik, 1983: 289). The genus Loxosceles comprises 140 species widely distributed around the world. These spiders are nocturnal, sedentary and remarkably nonaggressive, although they cause accidents in humans with wide degrees of severity, generating signs and symptoms that define the clinical condition known as loxoscelism.
